Didn't process request as i structed

Called in last month to cancel my recurring bundles. The call is visible on their system and the agent only cancel the data and not the minutes. This morning I see the minutes have been allocated again and immediately call in to inform them that this is not correct. But I get told I still need to pay for it even though it hasn't been used at all and the request can be traced requesting to cancel it. I am blocking their debit order till they fix the billing and will make a direct deposit for the amount that is due minis the airtime. Useless is what they are.
